Advanced Concepts/examples
In another example of an engine house I'll show you how I fixed an error.  I glued on the gable end and then cut out the doors. When I did, I accidentally went for the "two car garage door" look by removing the divider.  So, with a dab of hot glue rejoined the center divider. I added a tab of paper with some white glue for good measure.   Fixing minor errors and making changes is one of the things I really like about working the structure in foamcore.
